It's a bit hard to explain verbally for me but i'll try my best.
What I learned was, sine you're a righty, you hold up your right hand with the ball in it. Your elbow must be 90 degrees and your wrist should be pulled to the back. When you're about to shoot, hold the ball more to your fingers than your palm of your right hand. Your left hand should be at the side of the ball and your right should be around the bottom. Your right index finger should be pointing to your eye when you hold the ball. When you shoot, just flex your wrist.
I hope that helped.
